To all'whom it may concern.:

Be it known that @I CHARLEs SToLLBnRG, a citizen of the'United States,residing in Toledo, in the county of Lucas and State of hio, haveinvented a new and useful Improvement in Sheet-Steel Kegs, of which thefollowing is a speciiication.

My invention relates to im rovements in the construction of sheet steelegs or vessels for shi ment and handling of whlte lead and eavymaterials. The object of my invention is to provide a or vessel of astrong, simple, efficient and urable construction, adapted to be tightlyclosedand conveniently opened, which may be cheaply manufactured andwhich will be suitable for handling and shipment of white lead or otherheavy materials in the customary standard weight packages of a hundredpounds, lift-y ounds or other lilre amounts, and in which t e vessel-will not be liable to injury, or its cover to displacement when thesame are rolled or tumbled about, or even dropped from a wagon or aconsiderable height u ona stone avement whether the same str1 es uponits ottom or y 'to head, corner or side.

-interfolded hooks y invention consists in the novel'construction ofparte and devices and in the novel` combinations of arts and devicesherein shown and descri this ob'ect or result is accomplished..

In t e accompanying drawing forming a part of this speciiication,Figure` 1 is a central vertical section of a sheet metal Yor steel kegor vessel embodying my invention. Fig. 2 is an enlarged detail sectionalview Showing the construction at the upper and lower en s or corners ofthe vessel tal section on line 3-3 `of Fig. 1. detail artial elevation.

In tlhe drawing, A represents the Vsheet steel body of the vesse thesame being formed from a rectangular blank into cylindrical sha e, andhaving its meeting ends tightly an securely united by an externallyprojecting fold or lock seam a formed by the or edge folds al 0.2 on themeeting ends of the body blank, as will be Fig. 4 is a readilyunderstood from Fig. 3. ''Ihe lock ed, and by whichY and Fig. 3 1s ahorizon- B and cover D within,

upper end an externally projecting hoop acting curved'iiange crroll n.3snugly embracin the reinforcing or bracing circular wireor ro C whichsurrounds and externally stiffens and braces the upper end of the bodyand cooperates with the cover D to this end. The cover D vhas a deepcountersunk cylindric ,wall d and an' outwardly curved cover seat walld1 which snugly fits and embraces the cover seat wall a3 on the body A,the cover thus aHording a tight friction lit ,removable closurefor thevessel, and also serving to i11- ternally stiften and brace the upperend of the body.

The body A has at its lower end an external curved flan e or rolli4-which snugly surrounds and em races the external reinforcing wire orrod C1 at the lower end of the body.- The bottom head B has a deecountersunk cylindric wall b tting tight y and snugly within the lowerend of the body A -and it is also provided with an -outwardly curvedflange or roll b1 whichsnugly fits and embraces the external curvedfiange or roll a4 of the body that embraces the lower stiffening wireC1. The lower end of the body .is thus strengthened and stiffened andbraced not only by the external reinforcing wire or COMPANY, OFNW rodC?, but`also by the cylindrically curved flange or roll ai of the bodyand the similarly curved flange or rollt1 of the bottom head B.

'To insure a suitably tight joint or seam between the bottom head andbody, I interpose a suitable cement-like packing F between thecontacting parts of t e bottom head and body. Similar cement or packingG is also preferably inter osed between the contactlng surfaces of t ecover'D and body A. The cover D or its curved seat flange or roll d isfurnished with integral locking lips d which are hammered or clenchedunder the exter nal annular shoulder at the upper end of the body formedby the upper reinforcing wire C and the external flange or roll r1.3 endof the body which surroundsand ern-4 braces said stiifening wire C. Bothends of thefvessel are thus stiffened, strengthened and braced not onlyb external surrounding wires o r rods, but algo by double curved angesor rolls, the inner set of such iianges Il`or rolls being-integral withthe body and the outer set, one integral with the cover and the rotherintegral with the bottom head. These external s tiflening rolls at theupper and at the upper lower endszof the vessel also form annular'shoulders at both ends of the vessel for the same to roll upon, andthus materially facilitate. the handling and rolling about of the vesselwhen filled'with white lead or other heavy material. The deepcountersunk walls of theA cover and bottom head also aord a convenienthold for the lingers in lifting the heavy vessels when this isrequired..

1. 1n a sheet metal or steel vessel, for handling and shipment of white`lead or other heavy materials,.the combination of a cylindrical bodywithstieningrods or wires at each `end of the cylindrical body, integralexternally curved flanges or rolls at the upper and lower ends of saidbody embracing said stiffeninv wires or rods, adeep countersunk bottomiaving an outwardly curved integral flange surrounding and embracing thecurved flange or roll at the lower endof the body and a removable deepcountersunk cover havinGr an outwardly curved flange fitting andembracing said. curved flange or roll at the upper end of the body, andprovided with vintegral bendable locking lips clenched under said rollat the upper end of the body, said external rolls at the upper and lowerends of the body and said outwardly curved integral flanges of saidcover and bottom embracing said external rolls of the body being ofequal size and serving as rims for the rolling of the vessel as Well asto brace and strengthen the same, and for finger holds in lifting thevessel substantially as specified.

2.
